So she is a half-demon, her mother was killed because of it. Everyone got killed by the duke/mage, because her stepfather wanted to 'use' her later. Too brutal for me.
I dunno, he doesn't seem THAT friendly of a duke to me, least in these 2 chapters anyways. welp it is unfair to make complete judgements about his char but he just seems kinda sus to me ¯\_(ツ)_/¯
